Abstract
A preform (,) made of thermoplastic material and including a body (,) provided with an at least partially longitudinally extending inner partition (,). The preform is used for molding and particularly blow molding or stretch-blow molding a container with a body having opposed portions defining hollow recesses with inwardly-directed convex surfaces, said portions being spaced apart by said inner partition. In a straight cross-sectional view, the body (,) has a non-circular outline with two opposed portions (a, b) separated by a minimum distance (d,) that is smaller than the distances between the other pairs of opposed portions of said outline. The inner partition (,) extends between said two opposed portions (a, b), and said distance (d,) is such that, relative to the periphery of the body (,) of the preform, during molding, the inner partition (,) is transversely stretched at a rate equal to that at which the body (,) is transversely or peripherally stretched.
